Xamarin.Auth - Twitter

Question

在我的Xamarin Android中实现twitter登录有问题。我已经包含了Xamarin.Auth组件，它对Facebook很好。对于twitter auth.Completed事件不叫..。我在twitter开发门户上创建了示例应用程序。

下面是我在应用程序中的代码：

private void LoginTwitter()
    {
        var auth = new OAuth1Authenticator(
                  consumerKey: "3v7rOXkdexGYhQmr3HVhtGgPO",
                  consumerSecret: "mGhRjee87tAp4X0vHUmMIohWoYy0JGg9zFGyin7CigFP64y3j5",
                  requestTokenUrl: new Uri("https://api.twitter.com/oauth/request_token"),
                  authorizeUrl: new Uri("https://api.twitter.com/oauth/authorize"),
                  accessTokenUrl: new Uri("https://api.twitter.com/oauth/access_token"),
                  callbackUrl: new Uri("http://twitter.com")
              );
        auth.AllowCancel = true;
        StartActivity(auth.GetUI(this));
        auth.Completed += (s, eventArgs) =>
        {
            if (eventArgs.IsAuthenticated)
            {

                Account loggedInAccount = eventArgs.Account;
                //save the account data for a later session, according to Twitter docs, this doesn't expire
                AccountStore.Create(this).Save(loggedInAccount, "Twitter");
            }
        };
    }

我希望有人能帮忙。

Answer 1

好的，我自己解决了这个问题。创建新OAuth1Authenticator时，CallBack Url应设置为mobile.twitter.com而不是twitter.com

callbackUrl: new Uri("http://mobile.twitter.com")

在此之后，您将能够获得令牌。

希望它能对未来的人有所帮助。:)

编辑:你现在需要使用http://mobile.twitter.com/home -

我认为您需要移动您的Completed事件处理，因为我认为StartActivity阻塞了。

private void LoginTwitter()
{
    var auth = new OAuth1Authenticator(
              consumerKey: "3v7rOXkdexGYhQmr3HVhtGgPO",
              consumerSecret: "mGhRjee87tAp4X0vHUmMIohWoYy0JGg9zFGyin7CigFP64y3j5",
              requestTokenUrl: new Uri("https://api.twitter.com/oauth/request_token"),
              authorizeUrl: new Uri("https://api.twitter.com/oauth/authorize"),
              accessTokenUrl: new Uri("https://api.twitter.com/oauth/access_token"),
              callbackUrl: new Uri("http://twitter.com")
          );
    auth.AllowCancel = true;
    auth.Completed += (s, eventArgs) =>
    {
        if (eventArgs.IsAuthenticated)
        {

            Account loggedInAccount = eventArgs.Account;
            //save the account data for a later session, according to Twitter docs, this doesn't expire
            AccountStore.Create(this).Save(loggedInAccount, "Twitter");
        }
    };

    StartActivity(auth.GetUI(this));
}
